Domestic air conditioning means that traditional architectural features such as wide eaves, deep porches, thick walls, high ceilings, attics, and cross ventilation are no longer needed to promote natural cooling. Also irrelevant is siting or landscaping a house that maximizes summer shade and breezes, since mechanical equipment is able to maintain perfect indoor conditions independent of design.

Domestic air conditioning is most prevalent and ubiquitous in developed Asian nations such as Japan, Taiwan, South Korea, Singapore and Hong Kong, especially in the latter two due to most of the population living in small high-rise flats . In this area, with soaring summer temperatures and a high standard of living, air conditioning is considered a necessity and not a luxury.

Cooling capacity requirement is dependent on the room size. Generally, room air conditioners have a cooling capacity range between 5500 Btu per hour and 14,000 Btu per hour. Cool Climate Air Conditioning Systems will give total control over the environment at the click of a remote control by providing the exact temperature you require all year round. The costs of running a new air conditioning system may well be considerably less than your existing heating system, providing you with comfort at exceptional value to you and your home. Cooling power figures should be regarded suspiciously. It is best to look at both the input power and the heat transfer figures.

Split air conditioning is now an affordable investment. Most split air conditioning now comes with a heat pump and it is a very energy efficient means of heating during the winter months as well as cooling in the summer months. Split-type air-conditioning system can provide thermal comfort in small and large rooms. Moreover, the solar air conditioning is a newer system where the energy used for processing comfortable air is derived from the collected sun's rays.
